MG & Crab - yeeup, stylish arrival, and the girl dun good too (300hrs)
As for 2 tail rotors, yup there are some pretty silly ideas around, same with gearboxes, 2 of those too???
Control runs, duplicate? Even sillier what about 2 types of fuel incase one is contaminated?
Dual rotor head? KMax, either rotorhead can get to to the scene of the arrival??
What next? Two pilots? Ah yes that is good idea since 80% pilot error.
As for 2 engines, 600+? kg extra, for comfort (?) , why not, that seems sensible to some people?
